UNITED Sarns ATENT FORCE= PUMP.

SPECIFICATION forming part of Letters Patent No. 710,770, dated October7, 1902.

Application filed April 1'7, 1902.

To all whom it may concern:

Be it known that I, DANIEL L. FRIDDLE, a citizen of the United States,residing at Jackson, in the county of Clarke and State of Alabama, haveinvented certain new and useful Improvements in Force-Pumps, of whichthe following is a specification.

This invention relates to lift or force pumps; and the object of theinvention is to provide an induction-block and an exhaust-blockseparable from each other,'eaeh block being of peculiar interior formand of such novel arrangement that the parts maybe simply and quicklyassembled, and special means for connecting the blocks together and to apump-cylinder.

In the accompanying drawings, forming part of this application, Figure 1is a perspective view of my improved pump in position for operation.Fig. 2 is a cross-section of the valve-blocks with pipes and rod partlybroken away. Fig. 3 is a similar view in longitudinal section. Fig. a isa detail elevation of one of the valve-blocks. Fig. 5 is a crosssectionof a modification, showing a single valve-block with one of itsvalve-seats detachable and employing swinging flap-valves.

The same numeral references denote the same parts throughout the severalviews of the drawings.

The pump-rod 1,having a piston 2, is worked in a cylinder 3 by asuitable handle 4 and is held in vertical movable position by collars 5,secured to the pipe and having eyes 6 for said rod. This arrangement maybe varied as occasion may demand or according to the application of thepump, or it may be changed or dispensed with when it is desired to workthe pump by steam, windmill, or other motive power than by hand. Thepreferred form consists of rectangular blocks 7 and 8, of any suitablematerial,but preferably of hard wood. The induction-block 7 has acentral induction-port 9, provided with a screen or strainer andterminating at the inner end in a valveseat 10, formed in the end wall11 of a bore or cavity forming a pocket 12 for a ball-valve 13, which isloosely contained in the pocket by a bar or bars 14:. A semicircularbore 15 extends from the top surface of said block to the top wall ofand into the pocket 12, and

one of the bars 14 prevents the valve 18 from Serial No. 103,334. (Nomodel.)

closing said bore. It will be seen that the pocket 12 and valve-seat 10are formed by boring into the block from the inner face thereof. Theblock 8 is the same size and shape of the block 7 and has an exhaust orwater-discharge port 16 in its inner face and terminating at the innerend in a valve-seat 17, formed in the end wall 18 of a valve-pocket 19.This port, valve-seat, and pocket are formed by boring into the block 8from the outer face thereof. A semicircular bore 20 is made through thetop of the block 8 into the opening of the valve-seat 17, and theball-valve 21 is loosely held in the pocket 19 by a bar 22. In thisblock 8 it will be observed that the bore 20 does not communicate with apocket as the like bore of the other block, except through the valve 21.The blocks 7 and 8 are assembled with their inner faces engaging, sothat the exhaust-port of one block will be opposite the pocket of theother block and the two semicircular bores will form a circularcommunication for the pipe or cylinder 3. The cylinder 3 has a flange 23secured to the blocks by bolts 24, passed through and between theblocks, with a gasket between the blocks and the flange.

The exhaust pipe 1 is provided with a flange 25, secured to the block 8over the pocket 19 by means of bolts 26, with a gasket 27 betweenthe'bloek and the flange, and said bolts extend through both blocks atright angles to the bolts 2 1 to secure the blocks firmly together. Agasket 28 may be used bet-ween the blocks if desired.

Referring to the modification shown in Fig. 5, a single block isemployed, having pockets 29 and 30, the latter being provided with adetachable valve-seat or end wall 31, having a valve-seat and a fiathinged valve 32, and the pocket 29 has a like valve 33. In this form thevertical and horizontal bolts are dispensed with; but with thisexception and those above noted the device is the same as that firstdescribed.

It is obvious'that when the blocks are immersed,or partially so, inwater and the pumprod Worked such working will open and close the ballvalves and permit a continuous stream of water through the ports.

Having thus described my invention, what minating at said valve-seat, apocket extending outwardly from this seat and containing 15 aball-valve, the bolts securing the blocks together, and the bolts forconnecting the blocks in a pair to the pump-cylinder, substantially asset forth.

In witness whereof I hereunto set my hand 20 in the presence of twowitnesses.

DANIEL L. FRIDDLE.
